if two people attended; A and B, there'll be one handshake.

if three people attended; A, B and C.

round A:

A shakes B, A shakes C = 2 shakes.

round B:

B shakes A (already recorded), B shakes C =1 shake.

round C:

C shakes A (recorded), C shakes B(recorded) = 0 shake.


2 + 1 + 0 = 3 shakes in total.




if four people attended; A, B, C and D.

round A:

A shakes B, A shakes C, A shakes D = 3 shakes.

round B:

B shakes A (already recorded), B shakes C, B shakes D =2 shakes.

round C:

C shakes A (recorded), C shakes B(recorded) C shakes D = 1 shake.

round D: all recorded.

3 + 2 + 1 + 0 = 6 shakes.


most people should notice a pattern at this point.

if 5 people attended, there will be 4 + 3 + 2 + 1 shakes (10 shakes)



so if 14 people attended, there will be 13+12+11+10+9+8+7+6+5+4+3+2+1 shakes (91 shakes).





nice one efedua.

A boy forgot his pin code which was five digit,but luckily rememberd some hints onhw to remind him of his password,the following are the clues.(1)first digit is equal to the square of the second digit.(2)seconddigit + third digit=10....(3)fourth digit=second digit + 1...(4)fifth digit + third digit=14..(5)sum of all five digit make 30 find the pin

First digit is 9. 2nd is 3. 3rd is 7. 4th is 4. 5th is 7 .. So, 9 3 7 4 7 . d sum of doz numbers is 30.

ds is simple.......
Let d nos b ......
a b c d e
a=b^2;
b+c=10;c=10-b
d=b+1
e+c=14; since c=1=-b, :,e+10-b=14;e=4+b
and a+b+c+d+e=30
defining d equatn in terms of b,we av;
b^2 + b +10-b+b+1+4+b=30

b^2 + 2b +15 =30

b^2 + 2b - 15=0
(b^2 - 3b) (5b -15)=0

b(b-3) + 5(b-3)=0
(b+5) (b-3) =0
:, b=-5 or b=+3
since pin can nvr b negative,we pick +3


so, a=b^2 ;a=3*3=9

b=3

c=10-b; 10-3 =7

d=b+1 ;3+1=4

e=4+b;4+3=7

There4,d guy's pin is

d 2nd digit is 3...i jux got dat through trial n error..lol. Since d 1st digit is equal to d square of d 2nd digit then square of 3=9
1st digit 9.

3rd digit is 10-3( 2nd digit)=7.

4th digit is 3(2nd digit)+1=4.

5th digit is 14-7(3rd digit)=7.
So, 9,3,7,4,7.

5th digit is 14-7(3rd digit)=7.
So, 9,3,7,4,7.
